Radiator and Oil Pump Replacement - The 1947 - Present Chevrolet & GMC Truck Message Board Network

New to Posting.

I have a 94 K1500 Burb with 180k just purchased with hiway miles back and forth from NC to FL. Truck still has loads of power but the oil gauge seems to float under 40 psi at idle. 1) should I even mess with changing the oil pump with this many miles since I plan on swapping the motor when it finally does go or would it be wise to be preventative (or does this just indicate that it is finally going) and 2) the top radiator hose was removed by Sears

to flush out dead antifreeze and upon getting the truck back I find that the plastic radiator casing is cracked and is leaking -- anyone know of what recourse I can expect if any and also what type of radiator to replace the existing one with -- I'd like to upgrade bc the truck is rust free and I plan on keeping her awhile. Thanks

40 pis is fine now if it gets down to 10 start to worry.

The oil pressure is fine. Oil pumps (almost) never fail. They will last 300,000 miles or more.

Those radiators can be fragile. There are some all aluminum radiators that you can replace them with. Check Jegs and Summit.

My 89 GMC K-1500 does the same thing on oil pressure and it has 186,000 miles on it. I was going to have a new oil pump installed and my mechanic talked me out of it. He said my motor was just getting broke in. I'm planning to run it till it quits and then buy a new crate motor.
The plastic radiator went to leaking shortly after I bought the truck, and the best deal I found was on Ebay. There is a shop in Oklahoma that I dealt with. I could have bought a direct replacement, but opted for the all brass radiator instead. Haven't regretted it.
